Abstract

The purpose of this study is to obtain the horizontal magnification rate of orthopantomography. The subjects were consisted of 30 Korean adults who had Angle's classification I occlusion by using measuring wire set On the incisal edges of anterior teeth and the occlusal surfaces of premolars and molars along the dental arch. The results are as follows; 1. The average rate of total magnification was 115%. 2. The average rates of local magnification were the anterior teeth region was 90%, the canine region was 96%, the premolar region was 104%, the 1st molar region was 117% and the 2nd molar region was 124%.
